Can there be energy without time?

According to General Relativity, it is perfectly possible to have a spacetime with no matter and energy in it that still has a definite notion of time.

Can energy exist by itself?

No matter what the interactions are, energy is never seen to exist on its own, but only as part of a system of particles, whether massive or massless. There is one form of energy, however, that may not need a particle at all: dark energy.

Can energy exist outside of space and time?

Energy can exist without matter, because it is one in the same thing. Energy and time were created simultaneously in the big bang, so they are intertwined incessantly. And Space is an integral element of Cosmic cookbook that created the universe, so energy cannot exist without space.

How can energy exist?

It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. Energy can be neither created nor destroyed but only changed from one form to another.

Can there be time without mass?

Time and space cannot exist without mass and mass cannot exist without spacetime. As gravity potential increases so too do the dementions of space and time.

Can space/time exist without mass?

Can energy be defined?

Energy is defined as the “ability to do work, which is the ability to exert a force causing displacement of an object.” Despite this confusing definition, its meaning is very simple: energy is just the force that causes things to move. Energy is divided into two types: potential and kinetic.

Can energy be lost?

Energy can never be lost only distributed and changed. No, the law of conservation of energy states that energy cannot be destroyed (lost) or created – it can only change from one state of energy to another.

Can energy be stored in empty space?

So on the face of it – it seems that the answer should be no. However what about empty space – it certainly exists. Then there is no matter and hence no energy, and since also there is no matter space cannot be curved so energy can’t be stored in the curvature of space.

Can energy be incarnated as matter?

Einstein showed that energy is matter; for something to exist in a physical sense it must be incarnated as matter. So on the face of it – it seems that the answer should be no.

Is Energy conserved in space and time?

So at the very least you need a time dimension. You’re also going to need at least one space dimension for the energy to be anything other than trivial. (Otherwise, the conservation would just be “the energy is the same everywhere”, since it’s conserved in time and there’s only a time dimension.)

Can math exist outside of time?

So math can usefully exist outside of time, but anything that has energy cannot. This question originally appeared on Quora – the place to gain and share knowledge, empowering people to learn from others and better understand the world. You can follow Quora on Twitter, Facebook, and Google+.
